This is a normal response if you changed something on a battery driven device. So in case this is a baattery device, it should normally be written to the device the next time it wakes up automatically. Once in a while I have pushed the button write to device in the configuration screen.

Check the presently configured wake up interval. If it is very long, you may consider to reinclude the device, and set the interval much shorter temporarily, while you are playing with other settings.

I don't think this worked well before 2.2.4
Try setting parameter's using "Expert commands" instead of "configuration" Tab
Then in expert commands, scroll down to the configuration option.
When you set it here, the green light comes on as it receives the new setting.

I do basically have the same issue on some (but not all) devices. Unable to set certain values - just jumping back to the old value. So I used the "Expert commands" to set values the though way, but that worked. Little bit strange still...

All my 3 Fibaro FGS-222 suddenly reported "interview failed" in expert gui and started to grey out in standard gui and all the switches disappeared. It is as if they don't have any functionality anymore. The device descriptor is set to "Fibaro FGS222".

veeery strange. After digging into the command classes and the device descriptor I tried forcing a new interview (like for the 10th time, I wanted to see the network queue wile forcing a new interview) and suddenly all my switches are back. Why now? What was different? I don't know, it's a mystery to me.
